After trying different variations, I agree with Mark Fuller here, that passing values
through the URL or session is the best way to go. Benefits include:
- The result is bookmarkable.
- The target page is easier to test, because you can go directly to that state with a GET,
rather than first going through the other page.
I do recommend only passing boolean flags to note that you've changed state:
This keeps you in total control of the resulting output, while passing anything that then
gets displayed back as HTML is opening you up for an XSS attack.
